Which of the following is the maximum value of the equation?
Answer:
y = - x^2 + 2x + 5
= -(x^2 - 2x + 1) + 6
= -(x - 1)^2 + 6
-(x - 1)^2 always smaller or equal to 0
=> y is smaller or equal to 6
=> Option A is correct

1) The extent to which data points from a set of data differ from each other or from the true mean or average.
Answer:
measure of variability
Step-by-step explanation:
Measure of variability shows the extent in which data in a statically distribution differ from an average value as well as how they differ from each other. It shows how much the data falls from the center value (mean) showing the width of the distribution. The most used measures of variability are the range, interquartile range, variance, and standard deviation depending on the data to be measured.

Complete question
Nguyen is decorating the room for her sister's baby shower party. She is wrapping
Vietnamese conical hats in baby prints tissue paper to decorate the tables and some
shelves in the wall. Each hat has a diameter of 16 inches and a height of 9 inches. If
she wants to wrap 21 Vietnamese hats, how much tissue paper will she need?
A) 4,176 in²
B) 8,975 in²
C) 10,580 in²
D) 36,267 in²
Answer:
C) 10,580 in²
Step-by-step explanation:
The question above is solved by finding the Total Surface area of the the conical hats.
We are given the following values for each hats
Diameter of 16 inches , radius of the hat = Diameter ÷ 2 = 16 ÷ 2 = 8 inches
Height of 9 inches.
The formula for the Total Surface Area of a cone = πr[ r + √(h² + r²)]
= π × 8 [ 8 + √(9² + 8²)]
= 503.7 square inches or 503.7 in²
So, for one hat she would be needing 503.7 square inches or 503.7 in² of Vietnamese tissues.
We are told in the question that she wants to wrap 21 conical hats. Hence,
If 1 conical hats is wrapped with 503.7 in² of Vietnamese tissues.
21 conical hats =
21 × 503.7 in² = 10,577.7 in²
Approximately = 10,580 in²
Therefore, to wrap 21 Vietnamese hats, Nguyen would need 10,580 in² of tissue paper.
Here are the first five terms of a sequence.
3 8 17 30
47
Find an expression, in terms of n, for the nth term of this sequence.
Answer:
So the formula for the sequence is
Second term =first term + (a+nd)
Third term = second term + (a+nd)
And so on
Where n start with zero
Step-by-step explanation:
3 8 17 30 47
First term = 3
Second term = 8
Third term = 17
Fourth term = 30
Fifth term = 47
Second term - first term = 8-3=5
Third term - second term = 17-8= 9
Fourth term - third term = 30-17=13
Fifth term - fourth term = 47-30=17
So the AP is 5 9 13 17
We find out that the common difference is 9-5 = 4
The formula for nth term of the AP is
= a + nd
So the formula fir the sequence is
Second term =first term + (a+nd)
Third term = second term + (a+nd)
And so on
Where n start with zero

What is the value of x?
Answer: x = 27
Step-by-step explanation:
The angles (4x + 7) and 5(x - 4) are opposite angles formed by intersecting lines.
When intersecting lines form two sets of opposing angles, both pairs are equal in angle measure.
As such, the angles (4x + 7) and 5(x - 4) are equal. Knowing this, you can solve for x by setting the angles equal to each other in an equation:
[tex](4x + 7) = 5(x - 4)\\\\4x + 7 = 5x - 20\\\\27 = x[/tex]
X = 27.
How to write an analysis
Answer:
To write an analysis of a written text, start by outlining the topics you want to discuss, like the setting, characters, and themes. Additionally, gather quotations to use as evidence for each topic you plan to discuss. Then, begin your analysis with an introduction to summarize the text, followed by a thorough explanation of each topic.
Step-by-step explanation:
Arionna claims that since there are 3 feet in a yard, there are 9 cubic feet in a cubic yard. Which statement about her claim is true? Arionna is correct because there are 3 feet across the length of a cubic yard and 3 feet across the depth of a cubic yard. 3 times 3 = 9 Arionna is correct because there are 3 feet in a yard and there are 3 dimensions in a cubic yard: length, depth, and height. 3 times 3 = 9 Arionna is incorrect. There are only 3 cubic feet in a cubic yard because there are 3 feet in a yard, and the proportion will remain constant. Arionna is incorrect. There are 27 cubic feet in a cubic yard because a cubic yard is a prism with dimensions 3 ft Times 3 ft Times 3 ft. A prism with those dimensions will take 27 cubes to fill it if each cube is a unit cube of 1 ft.

Plz help!!! Calvin is filling the pool in his backyard with water. If the pool is in the shape of a cylinder with a diameter of 12ft and a height of 5 ft, how much water is needed to fill a 3/4 of the pool?
Answer:
424.1175
Step-by-step explanation:
Volume of the total pool = π[tex]r^{2}[/tex]h
= π x [tex]6^{2}[/tex] x 5
= 565.49
needed to fill a 3/4 of the pool = [tex]\frac{3}{4}[/tex] x 565.49
= 424.1175
Considering the volume of a cylinder, the amount of water needed to fill a 3/4 of the pool is 135π ft³.
Definition of volumeVolume is a measure of the space occupied by an object in three-dimensional space, using cubic units to measure it. The volume formula depends on the shape of the figure and its different dimensions.
Volume can be considered as the capacity of a container to hold a quantity of fluid (gas or liquid).
Volume of a cylinderIn the case of a cylinder, it is characterized by having two circular bases and a surface that joins the two bases. So the volume of a cylinder is π×r²×h.
Amount of water neededIn first place, you must know that the length of the radius is half the length of the diameter.
On the other side, it is needed to fill a 3/4 of the pool.
Then, considering the definition of volume and the expression of volume of a cylinder, the amount of water needed is calculated as:
amount of water=(3/4)×π×(12 ft ÷2)²× 5 ft
Solving:
amount of water=(3/4)×π×(6 ft)²× 5 ft
amount of water= 135π ft³
Finally, the amount of water needed to fill a 3/4 of the pool is 135π ft³.

I think is 11 but im not sure..
<12 and <11 are not linear pairs to <14
Explanation:
A linear pair is created when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
